Hello,all
   I'm using yaffs2 on Linux 2.6.20, our hardware supports Reed-Solomon ECC
Accelerator.
the HWECC generates 9-bytes of parity code for each 512 Bytes of data. So ,
in a 2K page,
the ECC parity code will take 36 bytes, and there're only 28 bytes left for
Yaffs2.
I found that yaffs2 need 32 bytes of Spare space, is that possible yaffs2
use less than 32 bytes? or
I need to give up using HWECC...

Thanks!
